The lack of power on consecutive days due to the instability of the electrical grid was what motivated the owner of Sítio Santo Antônio, João Gualberto Miguel, to install a photovoltaic system with energy storage on his site, located in Campinas (SP).
“Due to the lack of energy, since I'm at the end of the line, I run out of energy straight away. So, I'm opting for the hybrid generation system”, says the producer who also grows several fruits, including pitaya.
Initially, Miguel invested around R$ 2,200 in the purchase of six photovoltaic panels manufactured by Risen Energy.
The producer also purchased a 40 A Epever mppt charge controller and a 3 kW Growatt inverter.
Today, the site has 16 150 W photovoltaic panels, feeding a Growatt 3 kW inverter and four 170 Ah lead-acid batteries. In total, João spent R$ 12 thousand on the project.
“The house is 80% sustainable, it’s just not 100% because the showers have to be [operated] by grid power”, reports the owner.
According to Miguel, solar energy is also used to operate the electronic gate and the water pump for irrigating the pitaya plantation.
In total, it uses 2.5 kW, but it starts with utility power and then turns on the contactor switch to use solar power.
“I am very satisfied, I am not dependent on third parties, only on the Sun, which thanks to God, no matter how weak it appears, even when it rains, it meets all my needs”, says João.
